Microphone array and edge transcription
A counter-side system that picks up conversations at fixed service points and turns them into text. It is meant for shop checkouts, bank and government counters, pharmacy desks and consultation tables. In local mode the raw audio never leaves the device, and only structured, redacted text is sent on.

The problem
Counter noise ruins transcription, streaming branch audio to a central cloud costs bandwidth and exposes sensitive numbers, and single-channel recordings mix staff and customer voices.

Questions
Not in local mode. Audio is transcribed on the host and only redacted text is sent out. Cloud mode does send audio, so pick local mode for regulated counters.
Yes, depending on the host. The vendor benchmarks show 8 to 48 streams on the larger boxes, and 1 to 2 on the entry box.
The mic array cancels echo and suppresses noise by up to 20 dB, and its acoustic tuning is preset, so no on-site calibration is needed.
Tell us the site and the problem. We come back with a pilot plan and a priced hardware list.
